STAT() 

STAT(flag,filename)

(beginning Asterisk 1.4)

Returns status information about a file (compare the shell commands test and stat). The filename refers to an inode, so it can be a directory or a specific file. The flag can be one of the following:

d
Tests to see if filename is a directory.
e
Tests if the file exists.
f
Tests if filename is a regular file (as opposed to a special file, such as a block special file, character special file, symbolic link, named pipe, or socket).
m
Returns the mode of filename (octal), i.e. the permissions: e.g. 0754.
s
Returns the file size in bytes.
A
Returns the last access time (in Unix time).
C
Returns the last inode change time (in Unix time).
M
Returns the last modified time (in Unix time).
; See when /etc/crontab was last changed:
exten => 123,1,Set(foo=${STAT(M,/etc/crontab)})
